6 sin x − 3 sin 2x=12/π

You can solve this graphically in differnent ways.

The 2 online graphing calculators that I will recommend are Desmos and Wolfram|Alpha.

you can also do some graphing on the web2 calc.

https://www.desmos.com/calculator

I have done the plot on desmos so look here - you may have to zoom in or out to see it.

I have put y=LHS and y=RHS where the 2 graphs cross will be the solution points.

I have asked this question outright in Wolfram|Alpha
